Title: Improvements relating to arrangements for enhancing traffic safety
IPC: G08G1/16
Filed: 1956-11-26
Abstract: 857,703. Photo-electric braking control. MAILLOT, L., PICHON, R., GARNIER, F., BRUNEAU, J. and SOULIS, D. R. Nov. 26, 1956 [Nov. 25, 1955], No. 36083/56. Class 40(3). [Also in Group XXXI] Apparatus mounted on road vehicles to control their braking comprises a source of light, a photo-cell to receive light from other vehicles and an aerial to receive radio waves from stationary beacons, the output of the photo-cell and aerial being arranged to control a braking device to an extent corresponding to the strength of the signals. Such apparatus 1 adjustably mounted above the centre of the windscreen of a car comprises a horizontal polarization dipole aerial at the front, and, inside the casing, a source of ultra violet or modulated or oscillated light and a gas filled photo-cell with a monochrome filter each having a system of lenses. Light enters and leaves the stream-lined electrically insulated casing by way of slots in the front and sides. The forward angle of divergence is 23 degrees and the vertical 43 degrees. Light from another vehicle or reflected from a stationary beacon, or radio waves received from a stationary beacon produce a signal which is amplified at 2 to operate by means of an electro-magnet 12a, the valve 12 of a servomotor 11 which controls, by engine suction through a conduit 6, a master cylinder 10 associated with a fluid reservoir 13, to brake the hydraulic cylinders 3, 3a, 9, 14 of each wheel, and to light warning lamps on the dashboard. At the same time another electro-magnet (not shown) breaks the contact 18 between the car battery 4 and the distributer 19. Instead of stopping the motor by interruption of its electrical supply the throttle can be controlled to permit the motor to continue running during braking. The apparatus is powered by a generator 5. A valve 8 of the hydraulic system is connected to the brake pedal 21. The distributer 12 of the servomotor is controlled by an electro-magnet operating a slide valve (Fig. 4, not shown). In the circuit, Fig. 5, current from the photo-cell 44 or aerial 41 (after tuning at 71 and detection by a crystal 72) is fed, after elimination of the continuous component at 73, into the input side 70 of a two stage amplifier consisting ofa variable slope pentode 74 and a triode 75. The output is applied to a delayed threshold automatic gain control circuit 76, and a to differential control stage comprising two tetrode thyratrons 77, 78 of different ionization thresholds adapted to light green and red dashboard warning lamps successively by means of relays 80, 81. Manually controlled evasion of the signal source following operation of the green light prevents automatic application of the brakes. An auxiliary relay (not shown) is connected to the rear wheels to cancel the braking action when the vehicle slows down. Stationary optical beacons comprise two lens systems connected optically and mechanically and pointing in different directions. (Fig. 6 not shown, refers).

Abstract: 1,082,483. Transistor pulse circuits. RADIATION Inc. Sept. 7, 1964, No. 36537/64. Heading H3T. A solid slide relay circuit comprises two oscillators powered solely by the input signal and respectively operative for one or other polarity of the input signal, means being provided for rectifying the output of the oscillators to supply voltages which control respective transistor switches. When the telegraph input signal applied at 11, 12 is of one polarity the signal current flows through a diode 21 to energize a saturable core transistor oscillator 13. The output of this is rectified at 32 and 33 to bias seriesconnected transistors 36, 37 conducting so that a power supply 48 energizes a load 49. When the input signal is zero, neither oscillator oscillates and the load is not energized. When the signal is of opposite polarity, signal current flows through diode 26 to energize oscillator 14 arranged in a similar manner to oscillator 13 so that series transistors 38, 39 conduct and energize the load in the opposite polarity. Capacitors connected across the series transistors slow the rate of rise of output voltage and equalize transient voltages across the transistors.

Title: Improvements relating to seam welding
IPC: B23K13/04
Filed: 1957-03-13
Abstract: 851,529. 'Welding by pressure. MAGNETIC HEATING CORPORATION. March 13, 1957 [Feb. 6, 1957], No. 37944/59. Divided out of 851,528. Class 83 (4). In welding opposed edges of elongated metal portions by advancing the portions, maintaining the edges together at least in the region of a weld point, applying conductively to the portions current having a frequency of at least 100,000 cycles per sec. to flow in or adjacent to the edges in advance of the weld point to heat the edges to welding temperature, the impedance to current flow in at least one of the portions in a selected region corresponding to a desired current flow path is reduced by positioning an element of non-magnetic electrically conductive material adjacent to the selected region of the portion. In an embodiment in which the element or elements of conductive material are not shown a gapped metal tube 10, Fig. 1, is advanced by rollers 11, 12 which press the gap edges together at the weld point w and the edges are heated by current of 300 or 400 kc. per sec. applied to a contact 14 slidable on the upper surface of the tubing and the gap edges and to a grooved contact 20 slidable on the tubing upper surface before, at or beyond the weld point. The current flows from the contact 14 in parallel paths to the contact 20 and returns along a conduit 27 above the edges to concentrate the current in the edges. Cooling water &c. is supplied through the hollow supply conduits. The contact 14 may engage only the upper surface, only the edges, or only the inner surface of the tubing, the contacts may be rollers and the gap may be closed before the contact 14 is reached. In a modification in which the gap is closed before the contact 14a, Fig. 4, a further contact 20a engages the top of the rollers 11a, 12a so that current in parallel paths diverges at the weld point and passes through the rollers into contact 20a. The conductor 27a may be non-circular in this case. In a further embodiment, strips 35, 36, Fig. 9, of magnetic material and high volume resistivity, e.g. sintered magnetic oxide and insulated material or sintered non-carbonyl and synthetic resin are secured to the contact 14a alongside the conductor 27a and a strip of the conductive material, e.g. copper, is provided beneath the seam. Two strips of conductive material may be provided above the seam without a strip beneath the seam. In a further embodiment a pair of strips 50, 51, Fig. 12, are heated by current supplied by contacts carried by supports 55, 56 to flow along the gap edges around the weld point. Blocks of conductive material are adjustably mounted in holders 63, 64 and are cooled by jets of fluid from conduits 70, 71. An arrangement similar to that of Fig. 12 but with a single block of conductive material above the seam is employed for welding tubing and a rod of conductive material is mounted within the tubing. Specifications 748,528, 851,528 and 851,530 also are referred to.
